Model 11, 11A & 11A/11PS Calibrator for Balancer/Analyzers

The Calibrator allows the accurate calibration check and complete end-to-end functional check, at the customer's facility, of Chadwick-Helmuth balancer/analyzers. Models 11 & 11A operate on 28 VDC and the Model 11A/11PS on 110 VAC power.

In checking the overall calibration of the balancer/analyzer units, the Calibrator checks the following:

• Phase display
• Vibration amplitude
• Accelerometers or velocimeters
  
• High-temperature accelerometers
• Velocity coil transducers
• Strobex
• Magnetic pickup or photocell probe
  
• Interconnecting cables
